It’s a great app with huge potential, and I’m genuinely disappointed that we couldn’t use it in the end. If you’re looking for a product calculator, you’ll quickly realize this app is one of a kind on the Shopify App Store. Unfortunately, the developers seem to have overlooked that Shopify is designed for everyday people - many of whom don’t have a technical background but want to build their own websites. When you first install the app, you’re invited to book a free 15-minute setup call, which I did immediately. I was really eager to learn more, but to my surprise, no one showed up. I had to send two follow-up messages before someone finally joined the meeting after I’d already been waiting for 15 minutes. You’ll also run into a rather limited help section. Despite having studied at a math-focused high school and holding both a Bachelor’s and Master’s degree in finance, it still took me two days to fully understand how the pricing tables and formulas work. They’re actually not that complicated - but a clear, descriptive help section would have made a huge difference. Then come the real issues, which for us outweighed the benefits of keeping the app. For example, our product page would display one price, the “Add to Cart” button would show another, and the checkout would show yet another amount. The developers did offer workarounds, but most involved hiding values or options and adding information text instead - which didn’t feel like a proper solution. They also charge $350+ for their pre-made calculator templates, which I understand required time to build, and quoted us $800 just to make our checkout work with their app. And don’t be misled by the price shown on the app listing - to really use the app properly, you’ll need the Ultra plan, which is $120 per month. I was actually ready to pay all of that if the support had been responsive and reliable. Unfortunately, support replies typically took 24–36 hours. The app does offer great flexibility and visual design customization, but the technical side is really only manageable if you have your own developer. You’ll likely need to hire a developer for almost everything. I think the logic and potential behind the app are excellent - whoever is building it clearly knows what they’re doing - but they seem to forget that their customers are regular business owners selling t-shirts, stickers, body lotions, and other everyday products. I truly hope they invest more in their support and make the app more accessible - both for people who don’t have a technical background and in terms of budget.
